Waste Film Washing Recycling System
High-efficiency PP film washing line for cleaning and recycling post-consumer plastic film.
Installation & on-site training available.
Unit Introduction
Belt Conveyor
Used for conveying material, the surface of the belt is equipped with anti-slip devices and the height is adjustable.
Crusher
To crush the raw material into smaller pieces with water added during the process. The blade material is SK11.
Friction Washer
The high-speed rotating screw makes the material to be thoroughly scrubbed with water, effectively washing away its impurities.
Floating Washer
Used for separating sand, pulp, and other impurities from the raw materials. The main material used is stainless steel.
Dehydrator
High-speed centrifugal dehydration to remove moisture from the material and simultaneously eliminate residual impurities.
Squeezer
The material is squeezed and partially plasticizing through the screw compress, allowing for direct pelletizing with higher output.
Hot air dryer
For drying the material through hot air pipeline, which is also insulated with thermal insulation material to reduce energy consumption loss.
Control Cabinet
For control the operation of the entire line. Electrical components adopts famous brands such as ABB, Siemens, Omron, Schneider etc.

Working Process
Brief Description
After collecting the waste films, the first step is cutting or shredding, which converts the large rolls of waste films into smaller pieces. Then, these pieces will be fed into a sand removal machine for sand removal treatment. Excessive sand content will shorten the lifespan of the crusher blades and affect the washing quality.
The films, after the sand removal process, will enter the crusher for crushing. Water is added during the crushing process to facilitate initial washing. At the bottom of the crusher, there is a frictional washing and stripping machine to remove the sediment and dirty water from the material. The dried film will go to a high-intensity friction washer, which is specially designed by our company for removing sand from mulching films. This machine utilizes water for frictional cleaning, achieving a cleaning rate of over 99% for sand and sediment.
When finishing the washing process, the film flakes will go to a flotation washing tank for further rinsing. The rinsed film material will go to a squeezing machine for dehydration. Subsequently, the material can be processed by a granulator to produce granules.
Applicable Materials
PE Film Recycling: Washing and Crushing Result
Waste PE film is often contaminated with dirt, sand, and impurities before recycling. After passing through the washing, crushing, and separation process, the dirty film is transformed into clean PE film flakes. These washed flakes are suitable for further drying, pelletizing, or reuse in plastic manufacturing applications.
